an empty density bottle has a mass of 25g. its mass 1550g when full of water and 45g when full of another liquid. what is the density of the liquid in kgm-3​

The masses of the objects and their densities

Ithink the answer is c but then again i'm probably wrong

W= fd
where f is an applied force and d is the distance over which it is applied. when a parachuting skydiver is at constant velocity, he is experiencing "terminal velocity", the point at which his acceleration down is canceled out by air resistance. that means that the resisting force of the air is equal to his weight, but in the opposite direction. with this, we can solve for the work done by the force.
w = fd
w = (92.0)(9.81 m/s^2) (325)
w= 2.93 x 10^5 j
the value for work in this case is positive because it is pushing up on the skydiver, who has a downward force of gravity.
therefore the answer is 2.93 x 10^5 j

Answertechnician (a) is correct;
